Antero Midstream Partners LP (the “Partnership”) is a growth-oriented master limited partnership formed by Antero Resources Corporation (“Antero Resources”) to own, operate and develop midstream energy infrastructure primarily to service Antero Resources’ increasing production and completion activity in the Appalachian Basin’s Marcellus Shale and Utica Shale located in West Virginia and Ohio. The Partnership’s assets consist of gathering pipelines, compressor stations, interests in processing and fractionation plants, and water handling and treatment assets, through which the Partnership and its affiliates provide midstream services to Antero Resources under long-term, fixed-fee contracts. The Partnership’s consolidated financial statements as of December 31, 2017, include the accounts of the Partnership, Antero Midstream LLC (“Midstream Operating”), Antero Water LLC (“Antero Water”), Antero Treatment LLC (“Antero Treatment”), and Antero Midstream Finance Corporation (“Finance Corp”), all of which are entities under common control.
On September 23, 2015, Antero Resources contributed (the “Water Acquisition”) (i) all of the outstanding limited liability company interests of Antero Water to the Partnership and (ii) all of the assets, contracts, rights, permits and properties owned or leased by Antero Resources and used primarily in connection with the construction, ownership, operation, use or maintenance of Antero Resources’ advanced wastewater treatment complex in Doddridge County, West Virginia, to Antero Treatment (collectively, (i) and (ii) are referred to herein as the “Contributed Assets”). Our results for periods prior to September 23, 2015 have been recast to include the historical results of Antero Water because the transaction was between entities under common control. Antero Water’s operations prior to the Water Acquisition consisted entirely of fresh water delivery operations.
References in these financial statements to “Predecessor,” “we,” “our,” “us” or like terms, when referring to periods prior to November 10, 2014, refer to Antero Resources’ gathering, compression and water assets, the Partnership’s predecessor for accounting purposes. References to “the Partnership,” “we,” “our,” “us” or like terms, when referring to periods between November 10, 2014 and September 23, 2015 refer to the Partnership’s gathering and compression assets and Antero Resources’ water handling and treatment assets. References to “the Partnership,” “we,” “our,” “us” or like terms, when referring to periods since September 23, 2015 or when used in the present tense or prospectively, refer to the Partnership.
The Partnership’s gathering and compression assets consist of 8-, 12-, 16-, 20-, 24-, and 30-inch high and low pressure gathering pipelines, compressor stations, and processing and fractionation plants that collect and process natural gas, NGLs and oil from Antero Resources’ wells in West Virginia and Ohio. The Partnership’s water handling and treatment assets include two independent systems that deliver fresh water from sources including the Ohio River, local reservoirs as well as several regional waterways and other fluid handling assets which includes high rate transfer, wastewater transportation, disposal, and treatment.
The Partnership also has a 15% equity interest in the gathering system of Stonewall Gas Gathering LLC (“Stonewall”) and a 50% equity interest in the Joint Venture to develop processing and fractionation assets with MarkWest. See Note 11 – Equity Method Investments.
The Partnership’s financial statements are consolidated with the financial statements of Antero Resources (NYSE: AR), our primary beneficiary, for financial reporting purposes.
On April 6, 2017, in connection with its initial public offering, Antero Resources Midstream Management LLC (“ARMM”) formed Antero Midstream Partners GP LLC (“AMP GP” or our “general partner”), a Delaware limited liability company, as a wholly owned subsidiary, and, on April 11, 2017, assigned to AMP GP the general partner interest in us. Concurrent with the assignment, AMP GP was admitted as the Partnership’s sole general partner and ARMM ceased to be our general partner.
On May 9, 2017, ARMM closed its initial public offering. In connection with the offering, ARMM was converted into a Delaware limited partnership, and changed its name to Antero Midstream GP LP (“AMGP”).
